hey guys I'm brand new to Hp tuners although ive really been diving in to learn how to properly tune. i am currently working with obviously my LSJ engine with a p12 computer ive been looking al over the site and cant seem to find anything about being about to surpass the 2 bar restriction that these PCMs have. I'm looking to throw a bunch of boost to this motor and trying to figure out how other people are able to properly tune for boost over 17psi. thnx in advance.
